Concepts guiding the study of the impact of the built environment on physical activity for older adults in the community

社区环境与人类行为和身体活动之间的关系一直是健康促进领域的兴趣所在。健康的环境决定因素在文献中受到越来越多的关注，尽管在这一领域的实证研究很少。在本研究中，健康老年人和体弱老年人的身体活动与健康机构和娱乐设施的数量、良好的土地利用和社区安全（与犯罪、交通、环境危害和不文明行为有关）分别有显著关联。自然环境因素与户外体育活动行为具有一致的相关性。需要进一步的前瞻性研究来确定可能的因果关系。

The association between the neighborhood environment and human behavior and physical activity has been of interest to the field of health promotion. Environmental determinants of health are receiving growing attention in the literature, although there is little empirical research in this area. In this study, number of health institution and recreational facilities and good access to land use, and neighborhood safety (related to crime, traffic, environmental hazards, and incivilities) had significant associations with physical activity in healthy older adults and frail older adults, respectively. Physical environment factors have consistent associations with out-door physical activity behavior. Further prospective studies are required to identify possible causal relationships.
